The report said Iran still has not disclosed full information about its work on high-explosive testing and missile design work, as well as the "green salt project" studies -- research involving uranium tetrafluoride, a precursor to uranium hexafluoride, which is used in gas centrifuges to make enriched uranium.
"The agency has not detected the actual use of nuclear material" in the projects. However, they remain "a matter of serious concern," and clarification of them is critical to assessing Iran's past and present program, the report said.

Meaningless rhetoric, or something else. I mean if Iran basically sticks to their party line on this issue, what can really be done about it by the IAEA / UN?
